Distribution of CanSINE instances within the feliform/felid phylogeny. Ninety-three CanSINE insertion events are mapped onto a maximum-likelihood Feliformia/Felidae species tree reproduced using ~18 kbp of nuclear DNA from Johnson et al. [66]. Twenty-six subfamily I insertion events occurring in the feliform ancestor are indicated by the blue arrow box. Blue circles indicate 2 additional subfamily I CanSINEs in non-Felidae feliforms. Red and violet circles indicate more recent subfamily II type A and subfamily II type B insertions respectively. Solid circles denote fixed insertions present in all species within a lineage. Open circles denote unfixed insertions within a lineage (i.e. not all species in the lineage as presented have the insert). Approximate divergence times for discussed nodes are noted.
